As BADGRAPHICS said, this particular group of photos is meant to debunk the 'leaked' picture, which is the picture in the upper left hand corner. As you can see, the pikachu was taken from a real screenshot, appearing in the bottom left hand corner. It is probably the most well put together fake leak though. Kudos to the creator.
I don't really get what is being said about the windows though. Isn't it a good thing they're not identical?
Plus, the font of the percentages is just a little bit off (too tall).
